After the incident with my V940 showing the voltage display, it has never acted the same; I drove by a K speed sign one day and it stayed completely silent (I did a factory reset and it seemed to work the next time I drove by.) Today it would ramp all the way up before indicating the true strength of the threat. I think its time to send it in. Is there a good TS person at Beltronics that you guys have had a good experience with? Right now I just want to make sure everything is working well and that I dont rely on a faulty piece of equipment, if it is in fact faulty.
